Biomass pellet fuel is the use of corn stalks, wheat straw, rice straw, peanut shells, corn cobs, cotton stalks, soybean stalks, weeds, branches, leaves, sawdust, bark, tea seed husks and other solid wastes of crops. The raw materials are crushed, pressurized, densified, and formed into a modern clean fuel in the shape of small rod-shaped solid pellets. It is also a new and emerging biomass power generation fuel that can replace traditional coal.

The water consumption of this high return agricultural waste pellet plant for biomass fuel pellets project is 2415m3/a. The water source of this project comes from the municipal water supply pipe network of Gudian Township Industrial Park in Fengtai County, which is mainly used as emergency water source for production, life and fire fighting, which can fully meet the requirements of this 6t/h good quality cotton stalk biomass wood pellet line project.
The drainage system of the 6tph biomass energy pellet plant is divided into rain and sewage. The rainwater is discharged into the rainwater pipe network of the municipal engineering nearby. The 6t/h high quality biomass pellet line machine project does not produce production wastewater, and the wastewater is mainly domestic sewage and canteen wastewater from employees.
The generated domestic sewage and canteen wastewater are treated by grease traps and buried sewage treatment facilities, and the treatment reaches the first level of "Integrated Wastewater Discharge Standard" GB8978-1996, and is discharged into nearby ditches, and finally enters the Cihuaixin River. The displacement of this 6 tons turnkey biomass pellet plant for agricultural waste project is 1932m3/a.
The fuel pellet from biomass production line 6tph uses various crop straws, chaffs, etc. as raw materials. The 6 tons per hour new design fuel biomass pellet plant procedure consists of raw material crushing, pelletizing, and cooling. At the same time, each part is equipped with a strict quality monitoring system, ensure biomass pellets product quality. The specific biomass pelletizing plant agricultural waste pellet production process is shown in the figure below:
The raw materials of this 6tph agricultural waste biofuel pellet plant project come from wheat straw, chaff, corn stalks, etc. in the surrounding rural areas, and the bundled straws purchased are transported to the biomass pellet factory area and temporarily stored in the raw material warehouse in the biomass pelleting plant project area.
The purchased bundles of straw are delivered to the workshop warehouse by loaders, forklifts, etc., and manually loaded and unloaded to the conveyor. The straw conveyor adopts a closed structure. Some raw materials with higher moisture content will be dried in the drying yard before use.
Wheat straw and corn stalks are pulverized by a straw hammer mill, and can be granulated after pulverization. The raw material is less than 5mm after pulverization by straw hammer crusher.
Biomass pellet maker machine is the key biomass making equipment of the completely biomass wood pellet production line. Biomass pellet fuel pelletizer can be used for different raw materials such as rice straw, sawdust, corn stalk, bean straw, cotton straw and peanut shell, etc. The biomass pelleting machine is stable in operation. The density of processed pellet fuel can reach 0.7 to 1.4 tons/cubic meter.
The crushed materials by high capacity straw pulverizer are sent to the hoisting hopper through the conveyor, and the materials are sent to the feeding machine on the upper part of the biomass pelleting machine through the bucket elevator. The feeder sends the materials evenly into the pelletizing machine for biomass, and the produced pellets have a smooth surface and moderate hardness.
Friction is generated between the material in the biomass pellet press, the pressing roller and the template, which can generate a large amount of heat, and the temperature of the material is raised to about 80-110°C, so that the lignin is softened and sterilized.
The temperature of the biomass pellet fuel is as high as 80-90℃ when it is discharged from the biomass pellets plant pelletizing process. The structure is relatively loose and easy to break. It must be cooled by an air-cooled system and cooled to room temperature before bagging and storing.
The belt conveyor is sent to the biomass pellet cooling machine for cooling. The moving chain plate drives the pellets to move. The lower part has an air inlet and the upper part is equipped with a fan. The cooling is completed in 2-3 minutes. The cold sealing process is completed inside the electric pellet mill for wood biomass forage, which is closed and does not generate dust.
In this 6 ton biomass pellet plant design, a packaging conveyor is used for metering and in-belt packaging, and then sent to the finished product warehouse.
The biomass fuel straw waste pellet production plant project is located in Gudian Township Industrial Park, Fengtai County, and the land for the new hot biomass wood pelleting plant project is industrial land. According to the on-site survey, the rice husk straw wood pellet production plant project land is currently vacant and does not involve any remaining environmental issues.
The land used for the new setup biomass pellet plant project is industrial land, which meets the requirements of the city's overall planning and functional zoning. After adopting the pollution prevention and control measures specified in this environmental assessment, all pollutants can be discharged up to the standard. The impact on the environment is small, so the site selection of the 6t/h automatic completely biomass wood pellet production plant project is feasible and compatible with the regional environment.
The main problems we faced about biomass energy are dispersing resources and high cost of material collection. Except biogas energy which is mature basically, other kinds of biomass energy such as fuel pellets is still in the early stage of industrial development. Biomass materials have great potential as a kind of green fuel. Let's take straw recycling for example.
Years before, straw is seen as a kind of useless waste. Later in recent years, people gradually realized the significance of straw recycling. And the utilization of straw resources got great promotion. With the positioning of energy strategy, the utilization of biomass fuel pellet mill machine will bring a new round of opportunity for development in China.
China is a big country of agriculture. The yield of crop straw is increasing year by year. How to deal with the straw wastes have become the thorniest problems for new rural construction. Indiscriminate dumping and burning of crop straw is not only a waste of resources but also pollute our environment.
Backed by the national policy and support, the processing of straw fuel pellets, straw feed, straw coal will develop fast in recent years. Green fuel and green animal feed product is the best and right way to go.
At present, most provinces and cities of have list biomass pellet machines, animal feed pellet mill and biomass briquette press into the scope of financial subsidies. For the ones who want to start a small production business, biomass pellet plant, straw pellet plant and agriculture waste pellet plant production is a good opportunity!
